Windows 10 Mobile Creators Update now rolling out to the Release Preview ring

The Windows 10 Mobile Creators Update is now rolling out to Insiders in the Release Preview ring, despite the fact that the Creators Update for Mobile was supposed to roll out to the public today.
Microsoft says unsupported devices on the Release Preview ring will continue to receive cumulative updates for the Creators Update, which is nice. Previously, it was believed that unsupported devices would be left behind, but if you enrol in the Insider program, you'll still get cumulative updates for this unsupported release.
